Abstract

Designation of specific heating zones and increase in minimum resistance relative to prior heaters of the type to which the present invention pertains is achieved, together with flexibility or bendability, if desired, by slotting the outer conductor of the heater. Additional flexibility is also achieved by confining the high mu material only to those regions of the device where heating is desired, the unslotted regions.
